Constantine VII (Byzantine emperor)
Constantine VII (Constantine Porphyrogenitus), 905–59, Byzantine emperor (913–59). He acceded after the brief reign of his uncle Alexander, who succeeded Constantine's father, Leo VI. A regency (913–20) was followed by the rule (920–44) of the usurper Romanus I. In 945, Constantine expelled the sons of Romanus and began his personal rule. His main interests lay in legal reforms, in the fair redistribution of land among the peasants, and in the encouragement of art and learning. He was succeeded by his son, Romanus II.
